I picked up a Microsoft Bluetooth mouse today, thinking it would pair fine with my 17" PowerBook. Well, I followed the instructions from Apple's technote. The Bluetooth Setup Assistant "sees" the mouse, and properly identifies it as a Microsoft Mouse. When it attempts to pair, it just sits there. It's not locked up, because I can quit the Assistant normally, but it just sits there trying to pair. Before I return it, has anyone else has problems installing this mouse? All my system software is current - OS X 10.3.6, Bluetooth 1.5, Bluetooth Firmware Updater 1.1, etc. Was I just foolish to believe that Microsoft would implement industry standard Bluetooth (and not their own flavor, like they did with Java), or am I missing something??
